This invention relates to improvements in hy-' Another object of the invention is top'rovide an improved hydraulic back-supporting reclining chair having occupant controlled 'means for lowering the chair back to any desired angle between its vertical and horizontal positions, and

automatic means for slowly returning the chair back to its raised or vertical position when the occupant sits up in the chair after having reclined therein, or when the occupant leaves the chair. i

A further object of the invention is to provide an improved hydraulic back supporting reclining;

chair which will be highly efiicient in operation, and relatively inexpensive produce.

Other objects will appear as the description proceeds. 7

Like characters of references are used throughout the following specification and the accompanying drawings to designate corresponding parts.

In carrying out the invention, there is provided an improved hydraulic back supporting reclining chair having a substantially rectangular shaped chair seat frame generally designated by the reference numeral l formed by the opposite side rails 2 and 3, and the front and rear walls 4 and 5, respectively. Corner braces 6 of triangular shape are positioned in the corners of the frame I for reinforcing and strengthening the same.

Front legs 1 are provided at the front of the to manufacture and 2 Claims. (01. 155-160) 2 respectively.

2 chair frame I, and rear legs 8 are formed by the depending or lowermost ends of the rear arm supporting. members IO, which are secured to the seatfrarnel. 1

Frontarm supporting members II are secured to the forward and upper edges'of the side frame rails 2 and 3 of the seat frame 1, and horizontally disposed widened arm rests 12 are connected to theupper'ends of the members Ill and I I. Y

' Oppositely disposedinwardly extending stub shafts l3 and M are rotatably supported in the metal bearing collars l5 and I6 extending through the reararm supporting members lfl' adjacent the central portions thereof.

' A substantially rectangular'shaped back frame I! includes opposite siderails l8 and I 9 which are enlargedat their lower" ends, and connecting top and bottom rails, 20 and 2! respectively. The stub. shafts l3. and i4 are extended throughgthe enlargedlowerendsof. the side rails l8 andl9' of the back frame l1, for;providing'pivotal movement for'the b'ack frame J1, Suitable upg holstering for the seat frame and back frame is designated by the reference numerals 22 e e as,

' Heads and 25 are formed on the'inner ends of the stub shafts l3 and I4 and are attached to the side rails l8 and [9 of the back frame I! by bolts 15, while their cylindrical bearing spools or blocks 26 and 21 are formed on their outer ends, being secured by the keys 28 to the said stub shafts.

The arcuate metal braking or clamping bands 29 and 30 are hinged upon the hinge pin 3|, and terminate at their forward ends in the angled bearing heads 32 and 33 which are bored to slidably support the vertical rods 34 upon which the coil springs 35 and 36 are mounted respectively upon the upper and lower ends of said rods between the same and said heads 32 and 33. lhe coil springs 35 and 36 serving to close the heads 32 and 33 toward each other to provide a resilient clamping action by the bands 29 and 30 upon the bearing spools or blocks 26 and 21.

The forwardly extending arms 3'! and 38 are secured to the stub shafts l3 and I4 and support the upper ends of the coil springs 39 and 40, Whose lower ends are attached to the eyes Al secured to the rear outer surfaces of the seat frame side rails 2 and 3.

An operating lever 42 is provided with a handle knob 43 on its upper end, and is pivoted upon a pivot pin 44 suitably mounted on the chair arm, and has its lower end pivotally connected at 45 with the rearwardly extending actuating or releasing rod 46 upon which the brake releasing wedge head 47 of triangular shape, is secured for slidably engaging between the angled surfaces of the bearing heads 32 and 33 for separating and releasing the same when said handle knob 43 is moved forwardly, thus permitting the chair back to be pushed to horizontal position or to any angle between its raised and lowered position.

A hydraulic cushioning or closing device 48 is attached to the cross rail 49, disposed between the side rails 2 and 3 of the chair seat frame I, by means of the bolts 50, and is provided with a central shaft upon which a rearwardly extending operating arm 52 is mounted. A connecting link 53 is pivoted at 54 to the rear end of the arm 52, and is connected at its opposite end between the ears 55 on the bracket 56 attached by means of the screws 51 to the bottom rail 2| of the chair back frame IT.

The action of the hydraulic cushioning and closing. device willbe unrestrictedv as the back of the chair is moved to horizontal or reclining. po-

sition, at. which time the uphlostering 22' for the chair seat may be moved forwardly slightly. to provide a substantially horizontally disposed cushioned reclining surface.

Assoon as the occupant of the chair. moves,

from reclining position to sitting. position, or when leaving the chair, the hydraulic cushioning and closing. device with the assistance of the stretched coil springs 39 and 40 will automatically and slowly raise the seat back to its upright position.

From the foregoing, description, it will be apparent thatthere has been. devised and provided a highly efficient form of hydraulic back support- 4 claim as new and desire to secure by Letters Patent of the United States is:

1. An adjustable back reclining chair comprising a seat frame, chair side arms supported thereby, a chair back pivotally supported between said chair side arms, braking means associated with the chair back pivoting means for supporting said back at the desired angular inclination with respect to the chair seat including a cylindrical member rotated when the back is pivoted and a spring biased brake band on said cylindrical member, and a manually operated wedge member mounted for insertion between the ends. of said brake band to release said brake when desired.

2. An adjustable back reclining chair comprisingv a seat frame, chair side arms supported thereby, a chair back having pivotal support means for mounting the chair back between said chairside arms, braking means associated with said pivotalsupportzmeans to retainsaid back at the desired angular inclination with respect to said chair seat, and manually controlled means associated with said braking means for releasing said braking. means when it is desired to change the inclination of the back with respect to the chair seat, said support means including trunnion-like stub'sha-fts on said chair back, said braking means including braking bands clamping. one of said shafts and having bearing heads in spaced opposed relation, and said manually controlledreleasing means including a brake releasing wedge head slidably engaged between said bearing heads.
